Objective:To analyze the injury factors and prognosis of children with traumatic brain injury (TBI), and to explore the risk factors affecting its severity, so as to provide evidence for the prevention and intervention of TBI in children.Methods:A total of 6 040 children with TBI who were admitted to the Department of Neurosurgery of Children's Hospital of Soochow University from January 1, 2011 to December 31, 2020 were selected. The injury factors and prognosis were retrospectively analyzed. Univariate and multivariate Logistic regression analysis was used to analyze the factors affecting the severity of TBI in children.Results:Of the 6 040 children, 3 681 were males and 2 359 were females. The patients aged 1 to 3 years accounted for the highest proportion (34.0%, 2 056/6 040), and most of them were mild injuries (93.2%, 5 631/6 040). The main injury sites of children with TBI were road (35.9%, 2 167/6 040) and home (31.1%, 1 881/6 040), and the main causes of injury were falling from height (34.9%, 2 107/6 040) and falling (34.5%, 2 085/6 040). Children aged 1 to 3 years were most likely to be injured at home(41.9%, 861/2 056), mainly due to falling from height, while children aged 4 to 6 years were most likely to be injured on the road(43.8%, 828/1 891), mainly due to falling. Logistic regression analysis showed that children's residence, the presence of multiple injuries and the location of brain injury were independent influencing factors for the severity of TBI in children ( χ2=6.58, 138.15, 4.25, all P <0.05). Conclusions:TBI in children aged 1 to 3 years mainly occurred at home, and in children aged 4 to 6 years mainly occurred on the road. Falling from height and falling are the main causes of TBI in children. The society, schools and families should take targeted prevention education and intervention measures according to different age groups. Children who live in rural areas, have multiple injuries, and have multiple brain injury sites are more severely injured. In the process of treating children with TBI, the severity can be quickly predicted based on this, and the treatment efficiency of children with TBI can be improved.

Objective:To explore the influencing factors of residual thyroid clearance with 131I after surgery in patients with differentiated thyroid cancer (DTC). Methods:A retrospective analysis was conducted on the clinical data of 100 DTC patients admitted to the Hunan Provincial People′s Hospital from January 2018 to February 2021 who underwent 131I treatment for the first time. The success rates of first thyroidectomy using different doses of 131I, different pathological types, and different treatment times were compared, and logistic regression analysis was conducted to investigate the influencing factors of the efficacy of first postoperative 131I thyroidectomy in DTC patients. Results:A total of 54 patients successfully cleared residual thyroid, 46 patients failed to clear residual thyroid, and the success rate of clearing residual thyroid was 54%. The success rates of first clearance of residual thyroid in patients with 131I doses of 80 mCi, 90 mCi, and 100 mCi were 37.50%(12/32), 52.78%(19/36), and 71.88%(23/32), respectively, with statistically significant differences among the groups ( P<0.05); The success rates of first removal of residual thyroid in patients with follicular carcinoma, mixed papillary follicular carcinoma, and papillary carcinoma were 65.71%(23/35), 39.13%(9/23), and 52.38%(22/42), respectively. There was no statistically significant difference between the groups ( P>0.05); The success rates of first removal of residual thyroid in the group1 of patients (treatment time<3 months), the group2 of patients (treatment time 3-12 months), and the group3 of patients (treatment time>12 months) were 68.09%(32/47), 44.44%(16/36), and 35.30%(6/17), respectively. There was no statistically significant difference between the groups ( P>0.05); There was no statistically significant difference in the success rate of clearing residual thyroid in DTC patients of different genders, ages, pathological stages, and thyroid stimulating hormone (TSH) levels (all P>0.05); The difference in the success rate of clearing residual thyroid in DTC patients with different metastatic conditions and stimulating thyroid globulin (sTg) was statistically significant (all P<0.05); sTg, postoperative lymph node metastasis, and postoperative distant metastasis were independent risk factors for the efficacy of residual thyroid clearance in DTC patients for the first time after surgery (all P<0.05). Conclusions:The influencing factors for the efficacy of the first 131I in removing residual thyroid include differences in 131I dosage, presence or absence of metastatic lesions during treatment, Tg levels, etc. Reducing Tg levels is an important factor in improving remission rate, and controlling lymph nodes and distant metastasis is a key factor for the successful efficacy of the first 131I in removing residual thyroid.

Objective:To explore the factors affecting the safety of home environment for device-aided elderly people, so as to provide a basis for improving the safety of the elderly's home environment and promoting aging-adapted reform.Methods:From August 2021 to March 2022, stratified cluster sampling was used to select 326 device-aided elderly people from 8 communities in Urumqi City as the research subject. The survey was conducted using the General Information Questionnaire, Capacity Assessment Standard Table for the Elderly, Home Environment Safety Assessment Scale for the Elderly, and Home Environment Ageing-adapted Reform Cognition and Needs Concise Questionnaire for the Elderly. Multiple linear regression was used to explore the influencing factors of home environment safety for device-aided elderly people.Results:A total of 326 questionnaires were distributed, and 305 valid questionnaires were collected, with an effective recovery rate of 93.56% (305/326) . The influencing factors of home environment safety for device-aided elderly people included housing area, self-evaluation of the home environment, chronic diseases, monthly pension income, and cognition of aging-adapted reform ( P<0.05) . Conclusions:The aging-adapted reform of home environment should focus on elderly people who suffer from chronic diseases, have poor self-evaluation of the environment, have low monthly pension income and cognition of aging-adapted reform. Relevant departments should promote the self-evaluation methods of home environment and knowledge on home aging-adapted reform.

Objective To investigate the clinical effect of direct-acting antiviral agent (DAA) in the treatment of chronic hepatitis C (CHC) patients with thrombocytopenia and its effect on platelet count (PLT). Methods A retrospective analysis was performed for 83 CHC patients with thrombocytopenia (PLT < 150×10 9 /L) who received the DAA treatment regimen without interferon for 12-24 weeks in Tianjin Third Central Hospital from April 2018 to March 2019, and the changes in virologic response, liver function parameters, PLT, and liver stiffness measurement (LSM) were evaluated at the end of treatment (EOT) and at week 12 after EOT. Quantitative data accord with normal distribution were compared by repeated measures ANOVA. Normal transformation was performed before the comparison between skewed data, then repeated measures ANOVA was carried out. A logistic regression analysis was used to investigate the predictive factors for PLT elevation, and the receiver operating characteristic (ROC) curve was plotted to analyze the value of LSM in predicting PLT elevation after treatment. Results Among the 83 CHC patients with thrombocytopenia, 61.4% had liver cirrhosis, and the rate of sustained virologic response at week 12 after the end of treatment (SVR12) was 98.8%. From baseline to EOT and SVR12, the patients had significant reductions in the serum levels of aspartate aminotransferase, alanine aminotransferase, gamma-glutamyl transpeptidase, total bilirubin, and globin, a significant increase in the serum level of albumin, and a significant reduction in LSM (all P < 0.05). For all patients, PLT at EOT and SVR12 was significantly higher than that at baseline [EOT vs baseline: (110.4±44.6)×10 9 /L vs (97.8±33.2)×10 9 /L, P < 0.01; SVR12 vs baseline: (109.0±47.7)×10 9 /L vs (97.8±33.2)×10 9 /L, P < 0.01]. At SVR12, there were significant differences in the proportion of patients with liver cirrhosis, baseline LSM, and baseline white blood cell count between the PLT elevation group and the non-PLT elevation group (all P < 0.05). The multivariate logistic regression analysis showed that LSM was an independent predictive factor for significant PLT elevation after DAA treatment (odds ratio=0.929, 95% confidence interval: 0.864-0.999, P < 0.05). Baseline LSM had an area under the ROC curve of 0.644 in predicting PLT elevation, with a sensitivity of 81.0% and a specificity of 48.6% at a cut-off value of 20.15 kPa. The patients with PLT > 100×10 9 /L at baseline had a greater increase in PLT( P < 0.05). Conclusion CHC patients with thrombocytopenia have significant improvements in liver function and LSM after receiving DAA treatment and obtaining SVR12, and baseline LSM is an independent predictive factor for PLT elevation. There is a significant increase in PLT from baseline to EOT and SVR12.

ObjectiveTo investigate the risk factors for rebleeding within 5 years and the influencing factors for 5-year survival in patients with liver cirrhosis and severe esophagogastric variceal bleeding (EVB). MethodsA retrospective analysis was performed for 129 patients with liver cirrhosis who attended Tianjin Third Central Hospital from May 2012 to May 2014 due to severe EVB for the first time, with a follow-up time of 5 years. Related clinical data were analyzed, including age, sex, cause of liver cirrhosis, presence or absence of infection at the first time of bleeding, liver stiffness measurement (LSM), splenic stiffness measurement (SSM), portal vein diameter, biochemical parameters, rebleeding time, and prognosis. Esophagogastric variceal rebleeding was defined as the primary endpoint and death was defined as the secondary endpoint. The t-test was used for comparison of continuous data between two groups, and the chi-square test was used for comparison of categorical data between two groups; a logistic regression analysis was used to investigate the independent risk factors for rebleeding, and a Cox regression analysis was used to analyze the predictive indicators for 5-year survival in EVB patients; the Kaplan-Meier curve was used to analyze the cumulative non-rebleeding rate. ResultsAmong the 129 patients, 87(67.4%) experienced rebleeding during follow-up. There were significant differences between the rebleeding group and the non-rebleeding group in the proportion of patients with alcoholic cirrhosis (χ2=4.896, P=0.027), portal vein diameter (t=2.203, P=0.030), LSM(Z=-2.771, P=0.006), and SSM(t=2.678, P=0.010). The patients with alcoholic cirrhosis had a significantly higher mean number of times of bleeding than those with non-alcoholic cirrhosis (all P＜0.05). The multivariate logistic regression analysis showed that alcoholic cirrhosis (odds ratio ［OR］=5.687, 95% confidence interval ［CI］: 1.230-26.129, P=0.025), LSM(OR=1.039, 95% CI: 1.010-1.070, P=0007), and SSM(OR=1.078, 95% CI: 1.028-1.129, P=0.001) were independent risk factors for rebleeding within 5 years after treatment in EVB patients. Among the 129 patients, 45 (34.9%) died. The univariate Cox regression analysis showed that there were significant differences between the death group and the survival group in age, times of bleeding, mean arterial pressure, portal vein diameter, aspartate aminotransferase, lymphocyte percentage, and presence or absence of infection at the first time of bleeding (all P＜005). Further multivariate analysis showed that 5-year survival rate was associated with portal vein diameter (OR=1.459, 95% CI: 1056-2.014, P=0.022), age (OR=1.053, 95% CI: 1.006-1.103, P=0.026), times of bleeding (OR=1.286, 95% CI: 1.040-1.591, P=0.020), and presence or absence of infection at the first time of bleeding (OR=5.239, 95% CI: 1.750-15.641, P=0.003). ConclusionAlcoholic cirrhosis, LSM, and SSM are independent risk factors for rebleeding within 5 years in EVB patients, and age, times of bleeding, portal vein diameter, and presence or absence of infection at the first time of bleeding are associated with 5-year survival.

Objective:To assess the efficacy and safety of 100 units of botulinum toxin A (BTX-A) intradetrusor injection in patients with overactive bladder.Methods:From April 2016 to December 2018, 17 tertiary hospitals were selected to participate in this prospective, multicenter, randomized, double-blind, placebo-controlled study. Two phases of study were conducted: the primary phase and the extended phase. This study enrolled patients aged 18 to 75 years who had been inadequately managed by anticholinergic therapy (insufficient efficacy or intolerable side effects) and had spontaneous voiding with overactive bladder. Exclusion criteria included patients with severe cardiac, renal and hepatic disorders, patients with previous botulinum toxin treatment for 6 months or allergic to BTX-A, patients with urinary tract infections, patients with urinary stones, urinary tract tumors, diabetes mellitus, and bleeding tendency. Eligible patients were randomly assigned to BTX-A group and placebo control group in a ratio of 2∶1. Two groups of patients received 20 intradetrusor injections of BTX-A 100U or placebo at the depth of the submucosal muscle layer respectively under cystoscope, including 5 injections at the base of the bladder, 3 injections to the bladder triangle, 5 injections each to the left and right walls and 2 injections to the top, sparing the bladder neck. As a placebo control group, patients received same volume of placebo containing no BTX-A and only adjuvant freeze-dried preparations for injection with the same method. A combination of gelatin, sucrose, and dextran served as adjuvants. Average micturition times per 24 hours, urinary incontinence (UI) episodes per day, average micturition volume per day, OAB symptom score(OABSS), and quality of life (QOL) score were recorded at baseline and the 2nd, 6th and 12th week after treatment. The primary efficacy endpoint was the change from baseline in the average micturition times per 24 hours at the 6th week after treatment. The secondary efficacy endpoints included the change from baseline in the average micturition times per 24 hours at 2nd and 12th week, as well as the change from baseline in the OABSS, QOL score, average frequency of urgency and UI episodes per day, urgency score, average micturition volume per day at 2nd, 6th and 12th week after treatment. Patients were followed for 12 weeks to assess adverse events (AEs). After assessed at week 12, if the micturition times has decreased less than 50% compared to baseline and the patient is willing to receive retreatment, then patients could enter the extended trial phase. In that phase, patients in both groups were injected with 100 units BTX-A from 12th week onwards and then followed up the same indicators for 12 weeks.Results:216 patients were enrolled in this trial (144 cases in the BTX-A group and 72 cases in the placebo control group). Baseline characteristics such as age (47.75±14.20 in the BTX-A group and 46.39±15.55 in the control group), sex (25 male/117 female in the BTX-A group and 10/61 in the control group), and disease duration (0.51 years in the BTX-A group and 0.60 years in the control group) were balanced between the two groups( P>0.05). A marked reduction from baseline in average micturition times per 24 hours was observed in all treatment groups at the 6th week and the reduction of the two groups was statistically different ( P<0.001 and P=0.008 respectively). Compared with the baseline, the average micturition times per 24 hours at the 6th week decreased from baseline by 2.40(0.70, 4.60)times for the BTX-A group and 0.70(-1.00, 3.30) times for the placebo control group respectively, and the difference between the two groups was considered to be statistically significant ( P=0.003). The change rates of average micturition times per 24 hours from baseline at the 6th week of the two groups were (16±22)% and (8±25)% respectively, and the difference between the two groups was statistically significant ( P=0.014). Compared with the baseline, the average micturition times per 24 hours at 2nd and 12th week decreased by 2.00(0.00, 4.00)and 3.30(0.60, 5.03)for the BTX-A group, 1.00(-1.00, 3.00)and 1.70(-1.45, 3.85)for the placebo control group respectively. The difference between two groups was considered to be statistically significant ( P=0.038 and P=0.012); the changes of average urgency times per day for the BTX-A group and the control group at the 2nd, 6th and 12th week were 2.00(0.00, 4.30)and 2.40(0.30, 5.00), 3.00(0.30, 5.70)and 0.70(-1.30, 2.70), 0.70(-1.30, 3.00) and 1.35(-1.15, 3.50), respectively. There were significant differences between two groups at the 2nd, 6th and 12th week, ( P=0.010, P=0.003 and P=0.025, respectively). The OABSS of the BTX-A group and the control group at the 6th week decreased by 1.00(0.00, 4.00)and 0.50(-1.00, 2.00) compared with the baseline, and the difference between the two groups was statistically significant ( P=0.003). 47 cases of BTX-A group and 34 cases of placebo control group entered the extended trial phase, and 40 and 28 cases completed the extended trial phase, respectively. The average micturition volume per 24 hours changed by -16.60(-41.60, -0.60)ml and -6.40(-22.40, 13.30)ml, (-35.67±54.41)ml and(-1.76±48.69)ml, (-36.14±41.51)ml and (-9.28±44.59)ml, (-35.85±43.35)ml and(-10.41±40.29)ml for two groups at the 12th, 14th, 18th and 24th week, and the difference between two groups was statistically significant at each follow-up time ( P=0.01, 0.006, 0.012 and 0.016, respectively). There was no significant difference in other parameters( P>0.05). However, adverse reactions after intradetrusor injection included increased residual urine volume (27 in the BTX-A group and 3 in the control group), dysuria (21 in the BTX-A group and 6 in the control group), urinary infection (19 in the BTX-A group and 6 in the control group), bladder neck obstruction (3 in the BTX-A group and 0 in the control group), hematuria (3 in the BTX-A group and 1 in the control group), elevated alanine aminotransferase (3 in the BTX-A group and 0 in the control group), etc. During the follow-up period, there was no significant difference in the other adverse events between two groups except the increase of residual urine volume( P<0.05). In the primary trial phase, among the 27 cases with increased residual urine volume in BTA group, only 1 case (3.70%) with PVR more than 300 ml; the PVR of 3 patients in the placebo group was less than 100 ml. The increase of residual urine volume caused by the injection could be improved or disappeared with the passage of time. Conclusions:Intradetrusor injection of Chinese BTX-A improved the average micturition times per 24 hours, the average daily urgent micturition times, OABSS, and average micturition volume per time, and reduced the adverse effects in patients with overactive bladder.Chinese BTX-A at dose of 100U demonstrated durable efficacy and safety in the management of overactive bladder.

Point-of-care testing (POCT) has developed rapidly in various fields including medical health, customs quarantine, agriculture, graziery, forestry, fire-fighting, environment and food testing. It poses a huge challenge to the traditional inspection mode. Yet POCT still has many problems in terms of technical ability, quality control, regulation and industry-university-research cooperation and so on. Thus it is necessary for the health administrative departments, manufacturers and hospitals to establish consensus, and implement the total quality management system. The establishment of an independent evaluation system and the application of advanced quality control technologies of POCT is also essential given its particularity. This article focuses on the POCT application status and quality management in Shanghai based on the series of quality management measures for the POCT project carried out by the Shanghai Center for Clinical Laboratory, and raises some thoughts and suggestions for the existing problems.

Objective:To explore the job crafting behavior of male nurses and analyze its influencing factors.Methods:From April to June 2020, cluster sampling was used to select 250 male nurses from 10 Class Ⅲ hospitals in Henan Province as the research object. Nurses were investigated with the General Information Questionnaire, Job Crafting Scale and the General Self Efficacy Scale (GSES) . Single factor analysis of variance and multiple linear regression analysis were used to analyze the influencing factors of male nurses' job crafting behavior. A total of 250 questionnaires were issued in this study, and 231 questionnaires were effectively returned, with an effective recovery rate of 92.4%.Results:Among 231 male nurses, the total score of the Job Crafting Scale was (57.54±8.41) . Multivariate analysis showed that age, educational background, personal monthly income, and self-efficacy were the main influencing factors of male nurses' job crafting behavior with a statistical difference ( P<0.05) . Conclusions:Male nurses' job crafting behavior is at a medium level, and age, education, personal monthly income, as well as self-efficacy have an impact on it. Hospital managers should provide support for male nurses at the organizational level according to the influencing factors of job crafting behavior so as to improve their work shaping behavior level.

Objective:To summarize the patient profiles and therapeutic efficacies of ABO-incompatible living-related kidney transplantations at 19 domestic transplant centers and provide rationales for clinical application of ABOi-KT.Methods:Clinical cases of ABO-incompatible/compatible kidney transplantation (ABOi-KT/ABOc-KT) from December 2006 to December 2009 were collected. Then, statistical analyses were conducted from the aspects of tissue matching, perioperative managements, complications and survival rates of renal allograft or recipients.Results:Clinical data of 342 ABOi-KT and 779 ABOc-KT indicated that (1) no inter-group differences existed in age, body mass index (BMI), donor-recipient relationship or waiting time of pre-operative dialysis; (2) ABO blood type: blood type O recipients had the longest waiting list and transplantations from blood type A to blood type O accounted for the largest proportion; (3) HLA matching: no statistical significance existed in mismatch rate or positive rate of PRA I/II between two types of surgery; (4) CD20 should be properly used on the basis of different phrases; (5) hemorrhage was a common complication during an early postoperative period and microthrombosis appeared later; (6) no difference existed in postoperative incidence of complications or survival rate of renal allograft and recipients at 1/3/5/10 years between ABOi-KT and ABOc-KT. The acute rejection rate and serum creatinine levels of ABOi-KT recipients were comparable to those of ABOc-KT recipients within 1 year.Conclusions:ABOi-KT is both safe and effective so that it may be applied at all transplant centers as needed.

Objective:To explore the status quo of occupational stress and its influencing factors in junior nurses, and analyze the correlation and interaction between self -esteem, workplace violence and occupational stress. Methods:Totally 192 junior nurses working in 3 general hospitals in Zhengzhou from March to May 2020 were selected by convenient sampling, and investigated with the General Information Questionnaire, Self -Esteem Scale (SES) , Workplace Violence Scale (WVS) and Chinese Nurse Job Stressors Questionnaire (CNJSQ) . Totally 192 questionnaires were distributed, and 185 valid questionnaires were collected. Results:The SES, WVS and CNJSQ scores of the 185 junior nurses were (19.76±3.13) , (2.77±1.04) and (84.67±17.93) , respectively. There was statistically significant difference in occupational stress scores between nurses with different departments, job titles, marital status and physical condition ( P<0.05) ; the SES of junior nurses was negatively correlated with the scores of WVS and various dimensions of WVS ( P<0.05) ; The scores of WVS was positively correlated with various dimensions of occupational stress among junior nurses ( P<0.05) . Self -esteem had a significant mediating effect between workplace violence and occupational stress among junior nurses, and the mediating effect accounted for 12.86% of the total effect value. Conclusions:The occupational stress of junior nurses is at a moderate level, and their occupational stress is affected by many factors. Nursing managers can reduce their occupational stress by improving their self -esteem and reducing workplace violence.
